ATI TEAS 7 Exam Questions with 100%
Correct Answers | 2024/2025 Update
Enzymes are biological catalysts that ___________. - ✔✔Increase the rate
of any given reaction
Review the data in this table, and then choose the statement that draws the
best conclusion: - ✔✔Hours spent sleeping and score on the test correlate
with one another.
Dissolved oxygen (DO) is an important indicator of water quality, and
oxygen levels that are too high or too low can harm aquatic ecosystems. A
biologist noticed that fish were dying in a local lake and was concerned that
the DO levels were too low to support aquatic life due to extremely high
temperatures that summer. To measure the DO levels, she brought back
several lake water samples to her laboratory to measure the DO
concentration as a function of temperature. To do this, she heated several
samples of lake water to various temperatures and then measured the DO
concentration in each sample. Some samples were kept at the outdoors
temperature.
, Which of the following is the independent variable? - ✔✔Temperature
Why are control groups used in experiments? - ✔✔To minimize the effect
of variables
The same single-replacement reaction is run in two different beakers. The
beakers are labeled as Beaker A and B and are heated to 75ºC and 100ºC,
respectively. If the reactions are run for 15 minutes each, which of the
following results would you expect to observe? - ✔✔Beaker B produces
more product than Beaker A.
Which would be the approximate mass of a car? - ✔✔1,800 kg
**It's good to have a relative idea of the scale of various objects. The
average mass of a human is around 60 kg. The average mass of a car is
1,800 kg, and the average mass of a laptop is 2.5 kg.
Which of the following is the most plausible sequence of events? - ✔✔Born
into musical family; grows up around music; starts learning guitar; plays
concert
